Coal continues to play a outstanding position in energy technology in APAC. Fortunately, there are applied sciences and processes that assist us cut back carbon emissions from thermal technology.

The push in direction of a decrease carbon future has by no means been greater on the agenda for Asia Pacific, observes Osamu Ono, Managing Director and Chief Executive Officer at Mitsubishi Power APAC. With this motion, nonetheless, the query on how we are able to nonetheless embody coal within the equation has grow to be extra pronounced.

Coal stays one of many largest vitality sources of generated electrical energy throughout APAC, and there’s no signal of its position diminishing contemplating its continued presence on most vitality combine forecasts amongst international locations within the area for at the least the subsequent 10 years. Given current investments and the necessity to preserve grid reliability, it isn’t attainable to easily pull the plug on all coal-fired vegetation.

What is required is a stability between decarbonised but dependable energy. In an interview with Enlit Asia, Ono discusses how coal can stay related in as we speak’s vitality sector by way of biomass co-firing and new thermal energy and air high quality management methods.


Biomass is one potential gas supply for cleaner energy technology in Asia. “There is far promise on this renewable supply as biomass permits a discount in carbon dioxide (CO2) emissions of greater than 30% in co-firing circumstances,” says Ono, who notes that Mitsubishi Power is exploring its feasibility within the area.

Co-firing biomass with fossil fuels will deliver the area nearer to a decrease carbon future, however decarbonising energy in a area as complicated as APAC can’t be achieved by only a single entity. With this in thoughts, Mitsubishi Power continues to strengthen and type new partnerships with utilities, the trade, and academia to take steps ahead in reaching this ambition.

In October, the corporate signed a memorandum of understanding (MOU) with Indonesia’s PT PLN and Bandung Institute of Technology (ITB) with the aim of selling the adoption of biomass co-firing in Indonesia’s thermal energy vegetation. Through this MOU, Mitsubishi Power and its companions will perform research concerning the number of applicable biomass fuels, combustion evaluations, and gear modification plans in order to optimise the nation’s ample biomass potential. Economic evaluations shall be undertaken along with PLN, which operates quite a lot of coal energy vegetation in Indonesia. A coverage proposal together with applied sciences in addition to authorized and monetary assist frameworks for biomass co-firing initiatives is ready to be launched in 2021, which is able to then be adopted by the pilot undertaking’s improvement.

Technology Developments

Apart from biomass co-firing, one other method to cut back the dangerous environmental results from coal-fired energy vegetation is to enhance gas effectivity by upgrading current energy technology services, Ono suggests.

By putting in built-in coal gasification mixed cycle (IGCC) methods on the current coal vegetation, dangerous emissions together with CO2 could be decreased. IGCC, Ono explains, is a next-generation thermal energy system with considerably enhanced energy technology effectivity and environmental efficiency because of its mixture of coal gasification and a gasoline turbine mixed cycle (GTCC) system. Large-type IGCC methods can enhance energy technology effectivity by roughly 15% and cut back CO2 emissions in contrast with typical coal-fired thermal energy methods.

A GTCC energy plant, in the meantime, attains excessive effectivity by channelling the high-temperature exhaust gasoline from gasoline generators to drive steam generators for additional energy technology, describes Ono. Compared to traditional coal-fired thermal energy vegetation, GTCCs cut back CO2 emissions by 70%, offering an annual discount of seven million tons of CO2 from 1,400 MW of producing capability.

Furthermore, GTCCs supply the cleanest…
